In this post, you will see how you can iterate elements of an array in javascript.
Note: here we have an array of numbers.
We can find the number of elements in this array by using array.length i.e 6.
Now we will run for loop six times to print all the elements.
All of you know that array starts with 0 index. So if you initialize i with 0 then you have run loop until i ≤ (array.length-1) because we are starting from 0. Let's dive in the code now.
Code
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Iterate Array Using For Loop</title>
</head>
<body>
<script>
var array = [10, 20, 30, 40, 50, 60];
for(let i = 0; i<= (array.length-1); i++){
console.log(array[i]);
}
</script>
</body>
</html>
Output of this code will be;
10
20
30
40
50
60If you run for loop for more that array.length it will give you undefined value.
